Do giraffes make sound?
They don’t oink, moo or roar. But new research suggests perhaps giraffes do have a distinct sound: They hum. Beyond the occasional snort or grunt, the researchers recorded humming sounds that the giraffes made only at night.
Are giraffes related to dinosaurs?
No. Brachiosaurus was a dinosaur that lived around 150 million years ago. It takes less time to evolve longer bones than it does to change the total number, and this is an indication that the giraffe is more closely related to humans than to dinosaurs. In fact, our ancestries diverged just 110 million or so years ago.
What did giraffes used to be called?
Do giraffes have vocal cords?
Giraffes do have a larynx (voice box), but perhaps they couldn’t produce sufficient airflow through their 13-foot long (4 meter) trachea to vibrate their vocal folds and make noises. The researchers suspected the reason no one heard giraffe communication was because the sound frequency was too low for humans to hear.
